Sexual risk and testing for sexually transmissible infections in Aboriginal and Torres Strait Islander peoples and non-Indigenous young South Australians: results of an online survey.

Background Disproportionate rates of sexually transmissible infections (STIs) among Aboriginal and Torres Strait Islander young people are often attributed to risk-taking behaviours, but research rarely conducts direct comparison with their non-Indigenous peers to address this negative discourse. Methods 'Let's Talk About It 2019' was a cross-sectional online survey of South Australians (16-29 years). It prioritised recruitment of Aboriginal and Torres Strait Islander respondents to compare behaviours with non-Indigenous peers using multivariable Poisson regression models. Results Aboriginal and Torres Strait Islander (n =231) and non-Indigenous (n =2062) respondents reported similar condom use (40% vs 43%, P =0.477) and sexual debut median ages (16 years vs 17 years). Higher proportions of Aboriginal and/or Torres Strait Islander respondents reported a recent health check (48% vs 38%, P =0.002), STIs (60% vs 49%, P P =0.006) testing, STI diagnosis (29% vs 21%, P =0.042), and intoxication during last sex (30% vs 18%, P Conclusions Behaviours associated with STI transmission were mostly similar among Aboriginal and Torres Strait Islander and non-Indigenous respondents. Higher STI/HIV testing among Aboriginal and Torres Strait Islander respondents suggests effectiveness of targeted programs. Interventions targeting substance use and condom use among all young people are needed. Future interventions need to focus beyond behaviours and explore social determinants of health and sexual networks as contributors to disproportionate STI rates.

Genitourinary infection and gastroschisis: A systematic review and meta-analysis.

BACKGROUND: Gastroschisis is a congenital anomaly of the umbilical ring with increasing prevalence, especially amongst younger mothers. There is increasing evidence that exposure to genitourinary infections (GUTI) may play an important role in the etiology of gastroschisis. This systematic review and meta-analysis aimed to identify, appraise, and summarize the literature on exposure to GUTI and gastroschisis. METHODS: Six electronic databases (MEDLINE, EMBASE, Web of Science, Scopus, Cochrane Library electronic databases, and Prospero) were searched using a comprehensive search strategy. Citations and cited articles for all included studies were searched. Peer-reviewed, quantitative studies reporting an association of urinary tract infections (UTI) and/or sexually transmitted infections (STI) with gastroschisis were included. Prospero registration CRD42022377420. RESULTS: A total of 2392 papers were identified via the searches of which 15 met our inclusion criteria and were included after title and abstract and full text screening. The study period for included studies ranged from 1995 to 2016, most were from the USA. Four studies considering exposure to STIs and five to UTIs were eligible to progress to meta-analysis. Meta-analysis identified a significantly increased risk of gastroschisis in association with periconceptional exposure to UTI [OR 1.54 (95% CI 1.29, 1.8)], STI [OR 1.4 (95% CI 1.01, 1.79)]. CONCLUSIONS: Periconceptional exposure to GUTI is associated with an increased risk of gastroschisis. The prevention and timely treatment of GUTI amongst women of childbearing age may help to reduce the occurrence of gastroschisis.

Breaking barriers: How transwomen meet their healthcare needs.

BACKGROUND:  Transgender women - individuals assigned male at birth but who identify as female - are disproportionately affected by, among others, human immunodeficiency virus (HIV), other sexually transmitted diseases (STIs) and mental health issues. Studies show that transgender women often encounter discrimination and stigma when seeking healthcare from health facilities. AIM:  This study assessed the healthcare needs of transgender women, their experiences of the mainstream healthcare system and alternative strategies for navigating the healthcare system. SETTING:  The study was carried out in the City of Ekurhuleni Metropolitan Council in South Africa's Gauteng province. METHODS:  A case study design was followed. Participants were purposively selected and included 10 transgender women aged 26-50. Individual semi-structured interviews were conducted over 2 months. RESULTS:  Participants expressed a need for hormone replacement therapy, HIV treatment and prevention and treatment for STIs. Experiences of participants within the healthcare system were predominantly negative, with instances of discrimination, stigma and privacy violations being commonplace. Alternative strategies to meet their healthcare needs included the use of self-medication, consulting traditional healers and utilising non-governmental organisations. CONCLUSION:  There is an urgent need for equitable and inclusive health management of transgender women in South Africa.Contribution: This study provided a first look in a South African context into how and to what extent transwomen employ alternative healthcare strategies such as self-medication and utilising non-governmental organisations when faced with mainstream healthcare access barriers. The use of traditional doctors was identified as a novel, alternative strategy used by transwomen to access healthcare and treatment.

Unhealthy sexual practices among youth in Vhembe District, Limpopo province: A cross-sectional study.

Abstinence from sexual practice among youth not only prevents infections, HIV and AIDS, and unplanned pregnancies but also promotes healthy sexual practices and positive youth development. The study aims to explore and describe interventions to improve healthy sexual practices among youth in Vhembe district, Limpopo province. The study utilized a descriptive cross-sectional design with a sample size of 531 determined by the selected formular through probability, simple random technique. Using structured questionnaires for data collection from the participants. Validity was ensured and content and face validity. Reliability was ensured. Data was analysed using SPSS version 28.0. Ethical consideration was ensured during the study. The study results showed that 57.4% of the respondents indicated that they do not discuss their choice of contraceptive with their sexual partner, 80.6% of the respondents indicated that unplanned pregnancy can be prevented by supplying contraceptives programs at clinics and school while 83.2% of the respondents revealed that programs linked with contraceptive services can help prevent unplanned pregnancy. The study highlights the lack of contraceptive choice discussions among sexual partners, exposing them to risks of STIs, HIV and AIDS, and teen pregnancy, urging for improved healthcare access.

L'abstinence sexuelle chez les jeunes prévient non seulement les infections, le VIH et le SIDA et les grossesses non planifiées, mais favorise également des pratiques sexuelles saines et un développement positif des jeunes. L'étude vise à explorer et à décrire les interventions visant à améliorer les pratiques sexuelles saines chez les jeunes du district de Vhembe, province du Limpopo. L'étude a utilisé une conception transversale descriptive avec une taille d'échantillon de 531 personnes déterminée par le formulaire sélectionné par le biais d'une technique aléatoire simple et probabiliste.

Les données ont été analysées à l'aide de SPSS version 28.0. Une considération éthique a été assurée au cours de l'étude. Les résultats de l'étude ont montré que 57,4 % des personnes interrogées ont indiqué qu'elles ne discutaient pas de leur choix de contraceptif avec leur partenaire sexuel, 80,6 % des personnes interrogées ont indiqué que les grossesses non planifiées peuvent être évitées en proposant des programmes de contraception dans les cliniques et les écoles, tandis que 83,2 % des personnes interrogées ont indiqué qu'elles ne discutaient pas de leur choix de contraceptif avec leur partenaire sexuel. les personnes interrogées ont révélé que les programmes liés aux services de contraception peuvent aider à prévenir les grossesses non planifiées. L'étude souligne le manque de discussions sur le choix de la contraception entre les partenaires sexuels, les exposant aux risques d'IST, de VIH et de SIDA et de grossesse chez les adolescentes, et appelle à un meilleur accès aux soins de santé.

High STI burden among a cohort of adolescents aged 12-19 years in a youth-friendly clinic in South Africa.

Adolescents face a higher risk for HIV, STIs, and unintended pregnancy than any other age group in sub-Saharan Africa, and have unique health care needs as they navigate this period of growth and developmental milestones. We conducted the Youth Friendly Services study among adolescents in Rustenburg, South Africa to address some of these concerns. Participants aged 12-19 were followed quarterly for 12 months, asked at baseline about demographics, their sexual behavior, and tested for HIV, STIs, and pregnancy (girls). Report of sexual activity was not a requirement for enrollment. Assent and parental consent were obtained for participants under 18. Some follow up visits fell during COVID-mandated shutdowns, and we worked with participants to reschedule and extend follow up as appropriate. Here we present data on reported behaviors, participant attrition, risk of HIV, other STI, and pregnancy. From May 2018 to August 2019, we enrolled 223 HIV-negative, non-pregnant adolescents (64% girls). The median age was 17 (IQR: 14-18). Among the 119 (53%) participants who reported being sexually active at baseline, the median age at first sex was 16 years (IQR: 15-17). During follow-up, an additional 16 (7%) participants reported having their first sexual encounter. Among the sexually active participants, the incidence of HIV was 1.5 cases / 100 person-years at risk (PYAR, 95% CI: 0.4-6.0), the incidence of chlamydia was 15.7 cases (95% CI: 10.1-24.4), gonorrhea was 4.7 cases (95% CI: 2.1-10.5), and HSV was 6.3 cases (95% CI: 3.1-12.6); we observed no cases of incident syphilis. The incidence of pregnancy among sexually active girls was 15.0 pregnancies / 100 PYAR (95% CI: 8.5-26.5). Despite small numbers, the incidence of most STIs was significantly higher in females compared to males. We also observed two pregnancies and 5 incident STIs among participants who reported never having had sex, these tended to be younger participants. From March to September 2020, the clinic was shut down for COVID-19, and 53 study visits were postponed. Follow up was concluded in November 2020, a total of 19 participants were lost to follow up, however only one participant dropped off-study during COVID-19 shutdowns. Retention at the final visit was 91.5%. We successfully completed a prospective study of adolescents to learn more about the risks they face as they navigate sexual debut in the context of a program of youth-friendly counseling and services. Among self-reported sexually active participants, we observed a high rate of HIV, STI and pregnancy, however we also observed pregnancy and STIs among those who reported no sexual activity.

Evaluating knowledge, practice, and attitude of Syrian population on sexually transmitted infections and human immunodeficiency virus.

BACKGROUND: Human immunodeficiency virus (HIV) and sexually transmitted infections (STIs) can cause severe and fatal complications; knowledge about these diseases is essential for promoting safe sex practices and modifying behaviours that are harmful to one's health. This study investigates Syrian people's understanding, attitudes, and behaviors towards HIV/AIDS and STIs, aiming to identify factors promoting safe sex practices and modifying harmful behaviors. METHODS: This online cross-sectional study was conducted in Syria between 3 September and 23 November 2022, involving all 18+ individuals. The questionnaire was adapted from a previous study containing 74 questions from five sections: socio-demographic information, knowledge and practice regarding STIs, knowledge and practice regarding HIV/AIDS, attitude towards HIV/AIDS, and attitude regarding STIs and analyzed using descriptive and multivariate logistic regression. RESULTS: The study involved 1073 participants mostly aged between 18-30, with 55.3% females. Over half had good awareness of STIs and HIV/AIDS, with 55% and 63% respectively. Specifically, the overall knowledge level of STI type, signs/symptoms, risks of transmission, preventive methods, and complications for untreated STIs were (45.7%), (52.9%), (58.1%), (66.1%), and (59.6%), respectively. Medical field respondents had higher knowledge of HIV (P-value < 0.05, OR = 2). CONCLUSION: Our results show that Syrian people have a knowledge level of STIs and HIV was moderate. However, the attitude toward STIs was negative, as less than half of the participants had a good attitude. It is essential to solve these knowledge gaps, especially in low-income countries such as Syria.

Sexually transmitted infections among active component members of the U.S. Armed Forces, 2015-2023.

This report summarizes incidence rates and trends of sexually transmitted infections (STIs) from 2015 through 2023 among active component service members of the U.S. Armed Forces. The data compiled for this report are derived from the medical surveillance of chlamydia, gonorrhea, and syphilis as nationally notifiable diseases. Case data for 2 additional STIs, human papilloma virus (HPV) and genital herpes simplex virus (HSV), are also presented. The crude total case rates of chlamydia and gonorrhea initially rose by an average of 6.7% and 9.8% per year, respectively, until 2019. From 2020 onwards, rates steadily declined. By 2023, chlamydia rates had dropped by approximately 39%, while gonorrhea rates had fallen by more than 40% for female, and 19% for male, service members. Initially syphilis increased, on average, 10% annually from 2015 to 2019, then declined in 2020, but resumed its upward trend through 2023, nearly doubling the 2015 rate in 2023. The total crude annual incidence rates of genital HPV and HSV exhibited downward trends in general over the surveillance period, decreasing by 30.7% and 24.7%, respectively. Age- and gender-adjusted case rates for chlamydia, gonorrhea, and syphilis remain elevated within the U.S. Armed Forces compared to the general U.S. population, which may be due to factors that include mandatory STI screening, more complete reporting, incomplete adjustment for age distribution, and inequitable comparisons between the military active duty and general U.S. populations. Social restrictions enacted during the COVID-19 pandemic may have contributed to declines in true case rates and screening coverage.

Evaluation of artificial intelligence-powered screening for sexually transmitted infections-related skin lesions using clinical images and metadata.

BACKGROUND: Sexually transmitted infections (STIs) pose a significant global public health challenge. Early diagnosis and treatment reduce STI transmission, but rely on recognising symptoms and care-seeking behaviour of the individual. Digital health software that distinguishes STI skin conditions could improve health-seeking behaviour. We developed and evaluated a deep learning model to differentiate STIs from non-STIs based on clinical images and symptoms. METHODS: We used 4913 clinical images of genital lesions and metadata from the Melbourne Sexual Health Centre collected during 2010-2023. We developed two binary classification models to distinguish STIs from non-STIs: (1) a convolutional neural network (CNN) using images only and (2) an integrated model combining both CNN and fully connected neural network (FCN) using images and metadata. We evaluated the model performance by the area under the ROC curve (AUC) and assessed metadata contributions to the Image-only model. RESULTS: Our study included 1583 STI and 3330 non-STI images. Common STI diagnoses were syphilis (34.6%), genital warts (24.5%) and herpes (19.4%), while most non-STIs (80.3%) were conditions such as dermatitis, lichen sclerosis and balanitis. In both STI and non-STI groups, the most frequently observed groups were 25-34 years (48.6% and 38.2%, respectively) and heterosexual males (60.3% and 45.9%, respectively). The Image-only model showed a reasonable performance with an AUC of 0.859 (SD 0.013). The Image + Metadata model achieved a significantly higher AUC of 0.893 (SD 0.018) compared to the Image-only model (p < 0.01). Out of 21 metadata, the integration of demographic and dermatological metadata led to the most significant improvement in model performance, increasing AUC by 6.7% compared to the baseline Image-only model. CONCLUSIONS: The Image + Metadata model outperformed the Image-only model in distinguishing STIs from other skin conditions. Using it as a screening tool in a clinical setting may require further development and evaluation with larger datasets.

HIV vulnerabilities and psychosocial health among young transgender women in Lima, Peru: results from a bio-behavioural survey.

INTRODUCTION: Peruvian young transgender women (YTW) ages 16-24 years are a critical but understudied group for primary HIV prevention efforts, due to sharp increases in HIV prevalence among TW ages 25 years and older. METHODS: Between February and July 2022, a cross-sectional quantitative study with YTW ages 16-24 years in Peru (N = 211) was conducted consisting of a bio-behavioural survey accompanied by laboratory-based testing for HIV and sexually transmitted infections (STIs). Bivariate and multivariable Poisson regression models were used to estimate prevalence ratios between socio-demographic and behavioural characteristics and HIV status. RESULTS: HIV prevalence was 41.5% (95% CI: 33.9-49.4%), recent syphilis acquisition 19.4% (95% CI: 12.7-28.4), chlamydia 6.3% (95% CI: 3.1-11.1) and gonorrhoea 12.3% (95% CI: 7.9-18.7). Almost half (47.9%) reported condomless anal sex in the past 6 months, 50.7% reported sex work in the past 30 days and 13.7% reported accepting more money for condomless sex. There were no significant differences in reported sexual behaviours by HIV status. Only 60.8% of participants reported ever having been tested for HIV, and 25.6% reported a past 6-month STI test. More than two-thirds (67.8%) had not heard of antiretroviral pre-exposure prophylaxis (PrEP) and only 4.7% had taken PrEP in the past month. Current moderate-to-severe psychological distress was endorsed by 20.3%, 10.0% reported attempting suicide in the past 6 months and 85.4% reported alcohol misuse. CONCLUSIONS: Findings show that the HIV epidemic for YTW in Lima, Peru is situated in the context of widespread social exclusion, including economic vulnerabilities, violence victimization and the mental health sequelae of transphobic stigma that starts early in life. Future research should aim to further understand the intersection of these vulnerabilities. Moreover, there is an urgent necessity to design and evaluate HIV prevention programmes that address the root systems driving HIV vulnerabilities in YTW and that focus on developmentally specific clusters of stigma-related conditions.

Community contexts and knowledge: accountability, leadership and meaningful involvement of communities in Programme Science.

INTRODUCTION: A Programme Science approach that prioritizes populations who will benefit most and ensuring resources are allocated to programmes that meet the needs of those populations will bring an equity focus to research. Gay men and other men who have sex with men, people who use drugs, sex workers of all genders, and trans and gender-diverse people, defined by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and The Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund) as key populations, have been disproportionately impacted since the start of the HIV pandemic. Through documenting community experiences from global key population-led networks, the authors explore the potential value and impact of community-led organizations and service delivery as critical components in effective HIV and Sexually Transmitted infections (STI) programmes. DISCUSSION: Through advocacy and research interventions, global key population networks have identified barriers against scaling up interventions for criminalized and marginalized communities, as well as highlighted solutions. The authors examine some of the current barriers to meaningful involvement of communities and the scaling up of community-led programmes that need to be addressed if Programme Science is to maintain an equity lens and the needs of key populations are to be met and highlight the need to make visible community engagement and participation in embedded research and Programme Science. CONCLUSIONS: The Programme Science approach provides an important opportunity to understand practical issues that will increase effective coverage in the implementation of public health and other interventions, which will require the prioritizing of key populations and their priorities in HIV and STI programmes. It will require extensive time and work to build relationships, increase capacity and share power. Where this has already happened, it has resulted in positive outcomes, including better health outcomes, reduced stigma, increased agency for key populations, and built community-led organizations and responses.

Programme science methodologies and practices that address "FURRIE" challenges: examples from the field.

INTRODUCTION: "Programme science" deploys scientific methods to address questions that are a priority to support the impact of public health programmes. As such, programme science responds to the challenges of making such studies: (1) feasible to undertake, (2) useful, (3) rigorous, (4) real-world-relevant, (5) informative, and undertaken by (6) equitable partnerships. The acronym "FURRIE" is proposed to describe this set of six challenges. This paper discusses selected HIV/STI (sexually transmitted infection) programme science case studies to illustrate how programme science rises to the FURRIE challenges. DISCUSSION: One way in which programme science is made more feasible is through the analysis and interpretation of data collected through service delivery. For some questions, these data can be augmented through methods that reach potential clients of services who have not accessed services or been lost to follow-up. Process evaluation can enhance the usefulness of programme science by studying implementation processes, programme-client interactions and contextual factors. Ensuring rigour by limiting bias and confounding in the real-world context of programme science studies requires methodological innovation. Striving for scientific rigour can also have the unintended consequence of creating a gap between what happens in a study, and what happens in the "real-world." Community-led monitoring is one approach to grounding data collection in the real-world experience of clients. Evaluating complex, context-specific strategies to strengthen health outcomes in a way that is informative for other settings requires clear specification of the intervention packages that are planned and delivered in practice. Programme science provides a model for equitable partnership through co-leadership between programmes, researchers and the communities they serve. CONCLUSIONS: Programme science addresses the FURRIE challenges, thereby improving programme impact and ultimately health outcomes and health equity. The adoption and adaptation of the types of novel programme science approaches showcased here should be promoted within and beyond the HIV/STI field.

Prevalence and associated risk factors for men being paid for sex in Ethiopia: a multilevel analysis of 2016 Ethiopian demographic health survey data.

Paying for sex is considered a high-risk sexual behavior, especially among men. Men who pay for sex are perceived to be a bridge group for sexually transmitted illnesses. In sub-Saharan Africa, the prevalence of paid sex among men is approximately 4.3%. Men paid for sex are not studied in Ethiopia. Therefore, the objective of this study was to identify factors associated with men paying for sex in Ethiopia. We analyzed data from the 2016 Ethiopian Demographic Health Survey. In the analysis, 9070 men were included. To identify factors associated with paid-for sex among men, we used a multilevel logistic regression model. A p value less than 0.05 was considered to indicate statistical significance at the 95% confidence interval (CI). In this study, 509 (5.6%) men were ever paid for sex. Men who paid for sex were significantly more likely to be rich [Adjusted Odds Ratio (AOR) = 1.70; 95% CI 1.287, 2.246], widowed or separated (AOR = 1.97; 95% CI 1.142, 3.396), had more sexual partners [AOR = 1.03; 95% CI 1.005, 1.063], had ever been tested for human immunodeficiency virus (HIV) (AOR = 1.50; 95% CI 1.173, 1.916), drank alcohol (AOR = 4.15; 95% CI 3.086, 5.576), and chewing khat (AOR = 2.28; 95% CI 1.822, 2.85); men who had ever paid for sex were significantly less likely to have higher education (AOR = .63; 95% CI .438, .898) and the lowest age at first sex (AOR = .90; 95% CI .870, .924). In conclusion, educational level, wealth status, province, marital status, age at first sexual intercourse, number of sexual partners, HIV status, alcohol consumption status, and chewing khat were significantly associated with men's paid-for sex. From a public and sexual health perspective, more education is needed for illiterate, widowed, separated, and rich men. Additionally, preventive measures should be taken against men's behavior through the use of alcohol or khat, having many sexual partners, and having young men.

Improvement and exacerbation of multiple disparities in sexually transmitted infections among children and adolescents aged 6-22 years: An analysis of national surveillance data from 2013 to 2021.

To investigate the progress of disparities in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), gonorrhea, and syphilis among children and adolescents aged 6-22 years in China during 2013-2021. A total of 614 325 cases data were extracted from the Chinese Information System for Infectious Diseases Control and Prevention during 2013-2021. Puberty health education data were drew from the Student Health Surveillance in 2021. Disparity patterns and average annual percentage changes (AAPCs) in sexually transmitted infections (STIs) incidence or new cases in China were examined using descriptive statistics and joinpoint regression. The incidence across 345 cities was stratified by gross domestic product (GDP). Between 2013 and 2021, there were 614 325 reported cases of HIV/AIDS, gonorrhea, and syphilis among children and adolescents aged 6-22, with an annual average incidence of 24.0967 per 100 000. The expansion of HIV/AIDS has halted, yet the surge in gonorrhea and syphilis remains notably pronounced. The ratio of male to female AIDS incidence increased from 2.75 (2.60, 2.90) to 7.13 (6.68, 7.62), but that of syphilis changed from 0.33 (0.32, 0.34) to 0.56 (0.55, 0.57). Students and out-of-school individuals aged 13-15 experienced a notably high increase in STI cases, surpassing other age groups, with an average annual percentage increase of 29.2% and 26.3%, respectively. Nonstudents consistently had a higher incidence rate than students, with an IRR reaching 31.80 (31.24, 32.37) in 2021. A noticeable clustering pattern of new cases emerged in the southeastern region of the Heihe-Tengchong line, extending inland from the coastal areas. Districts and counties with lower rates of puberty sexual health education tended to have higher average STI incidence rates. At the prefecture and city levels, there was a noticeable upward trend on average STI incidence rates in cities with per capita GDPs. Strategies to address those disparities include promoting equitable health education, and widespread sexual health education, particularly in areas with limited access to education and experiencing rapid economic development. The effectiveness of sexual health education intervention needs to be further evaluated in well-designed studies.

The trend analysis of HIV and other sexually transmitted infections among the elderly aged 50 to 69 years from 1990 to 2030.

Background: The HIV and other sexually transmitted infections (STI) excluding HIV among the elderly population urgently require more attention and in-depth study. We aimed to present and predict the worldwide of its burden from 1990 to 2030 using data from the Global Burden of Disease (GBD) study. Methods: Leveraging the 2019 GBD study, we investigated the average annual percentage change (AAPC) of HIV and other STI in incidence, prevalence, disability-adjusted life years (DALYs), and mortality rates for individuals aged 50-69 across different age groups, genders, sociodemographic index (SDI) regions, and nations. The incidence of STI in the population from 2020 to 2030 was explored by Bayesian age-period-cohort (BAPC) prediction model. Results: The HIV incidence rate experienced its fastest growth 1990-1992, peaked in 1996, and gradually declined thereafter, with the 2019 rate being lower than that of 1990. The prevalence rate didn't present a sharp turning point. After 2006, its growth rate accelerated. Both DALYs and mortality rates plateaued high between 2002 and 2005, followed by a decline. The decline was steepest from 2005-2012, yet the rate of decrease slowed noticeably from 2012-2019.When segmented by age, HIV was more prevalent among those aged 55-59 and 50-54, with the 50-54 age group witnessing the fastest decline in incidence rates. However, the fastest growth in prevalence rates was seen among the 60-64 and 65-69 age groups. The other STI incidence rate declined from 1990-1996, increased up to 2006, declined until 2015, and then saw a resurgence with accelerated growth thereafter. The prevalence rate showcased varied trends, with a notable increase in the past five years. The highest growth in incidence rate was among the 65-69 age group. We predict that the incidence rate of STI will increase in the future. Conclusions: Overall, despite the evident decline in incidence, mortality rates, and DALYs, the prevalence of HIV and other STI among the elderly is rising, and both demonstrated significant trend variations across different ages, genders, SDI regions, and nations. Comprehensive sexual health education, clinical care and adjustments in health service strategies based on the evolving trends of HIV and other STI among the elderly are paramount.

Prevalence of Four Sexually Transmitted Infection Pathogens Detected in Urine and Genital Tract Secretion in Hangzhou, China.

BACKGROUND: Sexually transmitted infections (STIs) increase gradually and have become a public health problem in the world. UU, CT, NG, and MG are four common STI pathogens. Our retrospective study analyzed the clinical situation and the laboratory data of patients infected with the four pathogens. The prevalence of the four pathogens, detected in urine and genital tract secretion, was studied in Hangzhou, China. METHODS: A total of 3,168 male and female patients were randomly selected from February 2023 to February 2024. Urine and genital secretions were collected, and four STI pathogens were controlled for detection. Data were collected from the hospital's electronic medical records, and SPSS 25.0 software was used to perform a statistical analysis. RESULTS: Among 3,168 patients, a total of 1,527 were detected as positive, and the positive rate was 48.20%. The age of patients ranged from 13 - 98 years, with an average age of 45.6. The total of patients consisted of 2,191 males and 977 females, which had a significant difference (p < 0.05). Specimens were mainly collected from the Department of Dermatovenerology, Urological Surgery, Obstetrics and Gynecology, and so on. The positive rate was statistically different between male and female patients (p < 0.05). Single infection performed a main role and accounted for 79.57% of all of the positive patients. In the ≤ 20 age group, the positive rate was the highest and was as high as 77.65%. In detail, single infection caused by UU dominated, especially in the 21 - 30 age group. Double infection caused by UU and CT and triple infection caused by UU, CT, and NG were the majority, both especially in the 21 - 30 age group. There were significant differences in the positive rates in the different age groups and in the four pathogens (p < 0.05). Quadruple infection was very rare and had only been detected in one patient. CONCLUSIONS: The prevalence of the four pathogens in Hangzhou was different from other regions. More male than female patients, more single than multiple infections, and more single and multiple infections occurring in young people were the features in Hangzhou. The study would provide reference for prevention, diagnosis, and treatment of STI.
